The emergency repair work on the Grimburgwal quay wall, which collapsed on 1 September 2020, is now complete. Clean-up work has been carried out, an emergency structure with sheet piling has been erected and the quay in front of the UvA buildings is now back in use. The investigation into the causes of the collapse has also been completed.
The UvA commissioned geodata specialists Fugro to investigate the collapse of the quay wall, which was around 150 years old. Based on a comprehensive analysis of available data and visual inspections, Fugro’s final report concludes that multiple causes led to the quay wall collapsing:
The ownership of the quay was unclear until the incident. To identify the owner, the UvA commissioned historical research from the Netherlands’ Cadastre, Land Registry and Mapping Agency (Kadaster). According to the Kadaster, the UvA owns the section between the fencing (to the rear of the UvA buildings). The section along the public road and bridge is owned by the City of Amsterdam.
The cost of the repair work to date is approximately €1.1 million. This pertains to the investigation, the clean-up of the debris and the erection of an emergency structure with sheet piling. Due to the quay’s listed status, the UvA and the City of Amsterdam will work in tandem on the final repairs. It has been agreed that these final repairs will be complete within five years. The costs that this will entail are not yet known and will become clear after the final repair work has been put out to tender.
